Steve Langasek <steve.langasek@ubuntu.com> submitted some patches against downstream osmo-bsc 1.3.0 because some possible null derefences were detected by the compiler on Ubuntu s390x. Code has eveolved since then and patch doesn't apply directly anymore, since related code changed (we now use osmo_count in bsc_subscr_get). The compiled allegedly claimed some null dereference in gsm_lchan_name. In general code using that function seems to be doing checks for existing lchan before calling it, or assuming the lchan pointer is not null, so I couldn't find any major issue. However, let's add a OSMO_ASSERT to make sure we can easily identify the issue if an issue ever happens there, since the gsm_lchan_name should clearly only be called on non null pointers.

About OsmoBSC ============= OsmoBSC originated from the OpenBSC project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in typical GSM networks. OsmoBSC was one of the parts split off from the old openbsc.git. Before, it worked as a standalone osmo-bsc binary as well as a combination of libbsc and libmsc, i.e. the old OsmoNITB. Since the standalone OsmoMSC with a true A interface (and IuCS for 3G support) is available, OsmoBSC exists only as a separate standalone entity. OsmoBSC exposes - A over IP towards an MSC (e.g. OsmoMSC); - Abis interfaces towards various kinds of BTS; - The Osmocom typical telnet VTY and CTRL interfaces.
